Specification of Letters Patent. Patgntgd Dem 23, 1919.

Application filed February 5', 1919. Serial No. 275,110.

To all whom t may concern.'

Be it known that we, HOWARD H. HAMAn and WILLIAM E. SCHMIDT, both citizens of the `United States, and both residing at Three Oaks, in the county of Berrien and State of Michigan, have invented certain new and useful Improvements in Belting, of

`which the following is a specification.

Uurinvention relates `to improved means for securing stiffening strips to fabric, more particularly for securing transverse stiifening strips to fabric belting.

For stiffening fabric it is customary to sew strips cf other fabric or tape along the longitudinal edges to the fabric to form pockets into whichstiffening strips such as whalebone or featherbone are inserted. During bending or wear ofthe fabric the strips, when thus merely slipped into the pockets, may become displaced, turned or twisted, particularly when they are subjected to endwise pressure. The object of our invention is to prevent such displacement, turning or twisting and to keep the stiffening or stay members always in flat condition with reference to the base fabric. This is of particui lar importance in belting where the short transverse stiffening members are subjected to longitudinal pressure and abrupt bending. In accordance with our invention the stiften ing material or stays are sewn or otherwise secured to strips of fabric or tape and these strips of fabric or tape applied to the fabric to be stiffened with the stiffening material between the tape and fabric and the tape then sewn to the fabric along its edges. The

stays are thus not only held by the walls of Y the formed pockets but are also rigidly secured to one wall thereof and twisting, turning or displacement is prevented.

0n the accompanying drawing our improved construction and arrangement is clearly shown: p

lFigure 1 is a plan View of a length of belting showing transverse stiifening strips applied thereto at intervals.

Fig. 2 shows a length of tape to which a stay has been sewn.

Fig. 3 is a sectional view on plane 3-3, Fig. 2.

Fig. 1 isl an enlarged sectional view on plane 1- 4, Fig. 1.

Fig. 5 is an enlarged sectional view on plane 5 5', Fig. 1, and

stiening U stays `or strips.

Fig. 6 is an end view ofthe tape with a stay secured thereto and showing the longitudinal sides of the tape folded under before sewing to the base fabric.

l() represents a length of base fabric or belting whose longitudinal edges are protected by binding 11 and 12. 13 represents the transverse pieces of tape sewn to the base fabric and providing pockets for the In Fig. 2, 1% represents a length of tape to which a stiffening strip or stay 15 issecured longitudi nally as by stitching 16, thestrip being nar rowerthan the tape to permit the sides 17 and 18 of the tape to be turned under, as shown in Fig. 6. The tape withthe stiifening strips or stays secured thereto are then laid on the base fabric to be stiffened with the stays between the tape and the fabric. The tape lengths along their turned-in sides are then sewn to the fabric by stitching 19 and 2O which can very quickly be done by a two-needle sewing machine. The stiftening strips are now heldinqpoclrets formed by the base fabric and tape lengths and are further secured to one Wall of the pockets and are prevented from twisting, turning or becoming displaced, and will always lie fiat.

To form belting the tape lengths can be sewn along parallel lines to the base fabric and then the fabric cut into proper belting widths in a direction at right angles to the stays, and then binding applied to the belting thus formed, the binding passing over the ends of the transverse stays and their inclosing pockets. 0r, after the stiffening material has been sewn to tape lengths, the lengths can be cut up into pieces of a length equal to the width of the previously cut belting lengths t0 which they are to be applied. The small tape lengths are then sewn onto the belting and the binding 11 and 12 applied, as shown in Fig. 1.

Not only are the strips prevented from turning'or twisting but the mode of application is greatly simplified. By the old way the tape was first sewn on to the base fabric to form the pockets and the stays inserted therein. If thetape was not guided straight thrcu gh the machine during sewing or if the stitching lines came too close together it was difficult to insert the stays. With our improved procedure the stays are applied to the base fabric simultaneously with the pocket forming tape which supports them and the stays act to guide the tape during stitching ofthe same to -the base fabric. The stays could,"of course, be secured to the base fabric by stitching through the tape, base fabric and stays after the tape has been applied and the stays insertedthere'in. However; this will leave transverse stitching lines on the outside of the belting which would be-moreor less unsightly. Vith our arrangement such transverse stitching lines appear only on the back of the belting or stiffened fabric.

We do not, of course, desire to be limited to the exact construction, arrangement and operation shown and described, as modifications ,are no doubt possible which would still come within ,the scope of the invention. We Yclaim as follows:

1.1The combination with base fabric, of strips or tape lengths secured thereto along theirv edges to 'form pockets, and stays in said pockets, saidistays being stitched to one side of said pockets.V

2. The 'combination of base fabric'tobe e n stiifened, of tap@l lengths or strips sewn Yalong their edges to the fabric to form pockets, and stays or 'stiffening members in said pockets, said stays or stiffening members beingsewn to said tape or strip lengths forming said pockets. Y Y

3. The combination with fabric to be stiffened, of tape lengths or strips, stays or stiffening members secured to said tape lengths or strips intermediate their side edges, said tape lengths being` applied to the fabric with the stiifening members against the fabric, the tape lengths being sewn to the fabric along their longitudinal edges.v

1 4e. In belting, the combination of the base fabric, transverse strips or tape lengths sewn to the fabric along their edges to form Ipockets therewith, stiffening members or stays within said pockets, said stiifening members or stays being sewn to the transverse strips or tape, and binding along the edges of said fabric.

5. In belting, the combination of the base fabric, transverse strips or tape lengths sewn to the fabric along their edges to form pockets therewith, stiii'ening members or stays within said pockets, said stiffening members or stays being sewn to the transverseJ strips or tape, and binding along the edges'of said fabric. said binding receiving the ends of said tape lengths and the stiffening members secured thereto.

6. The process of stiffening fabric which consists in securing stiffeningmembers or stays to tape lengths, then applying the tape lengths to the fabric with the stifening stays against the fabric, and then sewing the tape lengths along their edges to the fabric.

In witness whereof, we have hereunto subscribed our names this 30 day of January, A. D., 1919.
